Mendelian inheritance is the manner by which genes and traits are passed from parents to their children, which can depend on genetics. Genetic variation is usually increased by meiosis. Take up this comprehensive test on Mendelian genetics and Meiosis process and get to learn more about human genetics. Have fun!
